What is Glycogen?

Glycogen is a naturally occurring polysaccharide composed of numerous glucose units arranged in a branched structure, primarily found in animal tissues like liver and muscle, or produced via fermentation from marine sources such as oysters or yeast. In cosmetic products, it belongs to the category of humectants and skin conditioning agents. It functions by drawing moisture from the environment into the skin's upper layers, helping to maintain hydration levels and improve skin texture. As a readily available energy source for skin cells, glycogen supports cellular metabolism and renewal processes. Typically incorporated into moisturizers, serums, creams, masks, and hair treatments at low concentrations, it enhances product feel and performance without greasiness.
